STARTING AND OPERATING125
“CLEAN FRONT WINDSHIELD” WARNING
The “ACC Limited Functionality Clean Front
Windshield” warning will display and a chime will
sound when conditions temporarily limit system
performance. This most often occurs at times of
poor visibility, such as in snow or heavy rain and
fog. The ACC system may also become temporarily
blinded due to obstructions, such as mud, dirt, or
ice on windshield and fog on the inside of glass. In
these cases, the instrument cluster display will
read “ACC Limited Functionality Clean Front
Windshield” and the system will have degraded
performance.
This message can sometimes be displayed while
driving in adverse weather conditions. The ACC
system will recover after the vehicle has left these
areas. Under rare conditions, when the camera is
not tracking any vehicles or objects in its path this
warning may temporarily occur.
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rearview
mirror. They may require cleaning or removal of an
obstruction. When the condition that created limited
functionality is no longer present, the system will
return to full functionality.
NOTE:If the “ACC Limited Functionality Clean Front Wind
-
shield” message occurs frequently (e.g. more than
once on every trip) without any snow, rain, mud, or
other obstruction, have the windshield and forward
facing camera inspected at an authorized dealer.
SERVICE ACC WARNING
If the system turns off, and the instrument cluster
display reads “ACC Unavailable Service Required”
or “Cruise Unavailable Service Required”, there
may be an internal system fault or a temporary
malfunction that limits ACC functionality. Although
the vehicle is still drivable under normal
conditions, ACC will be temporarily unavailable. If
this occurs, try activating ACC again later, following
an ignition cycle. If the problem persists, see an
authorized dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have
detection issues. In these cases, ACC may brake
late or unexpectedly. The driver needs to stay alert
and may need to intervene. The following are
examples of these types of situations:
TOWING A TRAILER
Towing a trailer is not recommended when
using ACC.
OFFSET DRIVING
ACC may not detect a vehicle in the same lane that
is offset from your direct line of travel, or a vehicle
merging in from a side lane. There may not be
sufficient distance to the vehicle ahead. The offset
vehicle may move in and out of the line of travel,
which can cause your vehicle to brake or
accelerate unexpectedly.

SERVICE THE PARKSENSE PARK ASSIST
S
YSTEM
During vehicle start up, when the ParkSense
System has detected a faulted condition, the
instrument cluster will actuate a single chime,
once per ignition cycle, and it will display the
"PARKSENSE UNAVAILABLE SERVICE REQUIRED"
message for five seconds.
If "PARKSENSE UNAVAILABLE WIPE REAR
SENSORS" or "PARKSENSE UNAVAILABLE WIPE
FRONT SENSORS" appears in the instrument
cluster display make sure the outer surface and
the underside of the rear fascia/bumper and/or
front fascia/bumper is clean and clear of snow,
ice, mud, dirt or other obstruction and then cycle
the ignition. If the message continues to appear
see an authorized dealer.
If the "PARKSENSE UNAVAILABLE SERVICE
REQUIRED" message appears in the instrument
cluster display, see an authorized dealer.
CLEANING THE PARKSENSE SYSTEM
Clean the ParkSense sensors with water, car wash
soap and a soft cloth. Do not use rough or hard
cloths. Do not scratch or poke the sensors.
Otherwise, you could damage the sensors.
PARKSENSE SYSTEM USAGE
P
RECAUTIONS
NOTE:
Ensure that the front and rear fascias/bumpers
are free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating properly.

Jackhammers, large trucks, and other vibrations
could affect the performance of ParkSense.

When you turn ParkSense off, the instrument
cluster display will read “PARKSENSE OFF.”
Furthermore, once you turn ParkSense off, it
remains off until you turn it on again, even if you
cycle the ignition.
ParkSense, when on, will reduce the volume of
the radio when it is sounding a tone.
Clean the ParkSense sensors regularly, taking
care not to scratch or damage them. The
sensors must not be covered with ice, snow,
slush, mud, dirt or debris. Failure to do so can
result in the system not working properly. The
ParkSense system might not detect an obstacle
behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle
is behind or in front of the fascia/bumper.
Use the ParkSense switch to turn the ParkSense
system off if objects such as bicycle carriers,
etc. are attached to the rear fascia/bumper.
Failure to do so can result in the system misin -terpreting a close object as a sensor problem,
causing the “ParkSense Unavailable Service
Required” message to be displayed in the
instrument cluster display.
NOTE:If any objects are attached to the bumper within a
6.5 ft (2 m) field of view, they will interfere and
cause false alerts and possibly blockage.
There may be a delay in the object detection
rate if the object is moving.
The rear sensors are automatically deactivated
when the trailer’s electric plug is inserted in the
vehicle’s tow socket. The front sensors stay
active and can provide acoustic and visual
warnings. The rear sensors are automatically
reactivated when the trailer's cable plug is
removed.
WARNING!
Drivers must be careful when backing up even
when using ParkSense. Always check carefully
behind your vehicle, look behind you, and be
sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before
backing up. You are responsible for safety and
must continue to pay attention to your
surroundings. Failure to do so can result in
serious injury or death.

STARTING AND OPERATING139
NOTE:The vehicle needs to be driven approximately one
car length in order for the Side Distance Warning
system to activate.
Operation With A Trailer
The system is automatically deactivated when the
trailer's electric plug is inserted in the vehicle's tow
hook socket. The rear sensors are automatically
reactivated when the trailer's cable plug is
removed.
ParkSense Usage Precautions
Some conditions may influence the performance
of the Side Distance Warning system:
NOTE:
Ensure that the front and rear bumper are free
of snow, ice, mud, dirt and debris to keep the
ParkSense system operating properly.
Construction equipment, large trucks, and
other vibrations could affect the performance
of ParkSense.
When you turn ParkSense off, the message
in the instrument cluster display will read
“PARKSENSE OFF.” Furthermore, once you turn
ParkSense off, it remains off until you turn it on
again, even if you cycle the ignition key.
ParkSense, when on, will reduce the volume of
the radio when it is sounding a tone.
Clean the ParkSense sensors regularly, taking
care not to scratch or damage them. The
sensors must not be covered with ice, snow,
slush, mud, dirt or debris. Failure to do so can
result in the system not working properly. The
ParkSense system might not detect an obstacle
behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle
is behind or in front of the fascia/bumper.
The presence of a tow hook without a trailer may
interfere with the correct operation of the
parking sensors. Before using the ParkSense
system, it is recommended to remove the
removable tow hook ball assembly and any
attachments from the vehicle when it is not
used for towing operations. If you leave the tow
hook fitted when not towing a trailer, the tow
hook could be detected as an obstacle by the
sensors. Contact your authorized dealer to
update the ParkSense system operations.
WARNING!
Drivers must be careful when backing up even
when using ParkSense. Always check carefully
behind your vehicle, look behind you, and be
sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before
backing up. You are responsible for safety and
must continue to pay attention to your
surroundings. Failure to do so can result in
serious injury or death.

Before using ParkSense, it is strongly recom -
mended that the ball mount and hitch ball
assembly be disconnected from the vehicle
when the vehicle is not used for towing. Failure
to do so can result in injury or damage to vehi -
cles or obstacles because the hitch ball will be
much closer to the obstacle than the rear
fascia when the vehicle sounds the continuous
tone. Also, the sensors could detect the ball
mount and hitch ball assembly, depending on
its size and shape, giving a false indication that
an obstacle is behind the vehicle.

22_MP_OM_EN_USC_t.book Page 139

STARTING AND OPERATING145
The sensors may not detect objects of a partic -
ular shape or made from particular materials
(very thin poles, trailer beams, panels, nets,
bushes, anti-parking posts, pavements, rubbish
bins, motor vehicles, etc.). Always take great
care to check that the vehicle and its path are
actually compatible with the parking place iden -
tified by the system.
The use of wheels and tires that are different
size to the original equipment could affect the
operation of the system.
The operation of the rear sensors is automati -
cally deactivated when the trailer's electric plug
is inserted in the vehicle's tow hook socket,
while the front sensors stay active and can
provide acoustic and visual warnings. If this situ -
ation occurs, Active Park Assist will not work.
The rear sensors are automatically reactivated
when the trailer's cable plug is removed.
In "Search in Progress" mode, the system could
incorrectly identify a parking place to carry out
the maneuver (e.g. by a junction, driveways,
roads crossing the direction of travel, etc.).
In the case of parking maneuvers on roads with
inclines, the performance of the system could
be inferior and it may deactivate.
If a parking maneuver is being carried out
between two parked vehicles alongside a curb,
the system may cause the vehicle to drive up
onto the curb.
Some maneuvers at very tight bends might be
impossible to be carried out.
Take great care to ensure that conditions do not
change during the parking maneuver (e.g. if
there are persons and/or animals in the parking
place, moving vehicles, etc.) and intervene
immediately if necessary.

During parking maneuvers, pay attention to vehi -
cles approaching from the opposite direction.
Always abide by the law and road regulations.

NOTE:
Correct system operation is not guaranteed if
snow chains or the compact spare tire are fitted.
The function only informs the driver about the
last appropriate parking place (parallel or
perpendicular) detected by the parking sensors.
Some messages displayed are accompanied by
acoustic warnings.
ACTIVE LANE MANAGEMENT SYSTEM —
IF EQUIPPED
ACTIVE LANE MANAGEMENT OPERATION
The Active Lane Management (ALM) system uses a
forward facing camera to detect lane markings or
road edges and measure vehicle position within
the lane boundaries. It also uses the Blind Spot Monitoring sensors to detect vehicles in adjacent
lanes while the driver is preparing to change lanes.
The system is operational at speeds above 37 mph
(60 km/h) and below 112 mph (180 km/h).
When both lane markings are detected, and the
vehicle drifts out of the lane (no turn signal
applied), the Active Lane Management system
provides a visual warning in the instrument cluster,
as well as a steering assist torque (if configured in
Uconnect Settings), to prompt the driver to remain
within the lane boundaries. If the driver continues
to drift out of the lane, the system provides a
flashing visual warning through the instrument
cluster display as well as a haptic steering wheel
vibration (if configured in Uconnect Settings) when
the vehicle crosses the lane boundary.
The warning will be in the form of a vibration in the
steering wheel, and/or automatic steering
assistance to direct the vehicle back toward the
center of the lane.
When both lane markings are detected, and the
driver uses the turn signal to indicate a lane
change while the system detects another vehicle in
the Blind Spot Monitoring zone on that side of the
vehicle, the Active Lane Management system
provides a warning in the form of steering assist
and/or steering vibration (depending on radio
settings) to guide the vehicle back to the center of
the lane.

154STARTING AND OPERATING
The entire vehicle should first be weighed on a
commercial scale to ensure that the GVWR has not
been exceeded. The weight on the front and rear of
the vehicle should then be determined separately
to be sure that the load is properly distributed over
the front and rear axle. Weighing the vehicle may
show that the GAWR of either the front or rear axles
has been exceeded but the total load is within the
specified GVWR. If so, weight must be shifted from
front to rear or rear to front as appropriate until the
specified weight limitations are met. Store the
heavier items down low and be sure that the
weight is distributed equally. Stow all loose items
securely before driving.
Improper weight distributions can have an adverse
effect on the way your vehicle steers and handles
and the way the brakes operate.
TRAILER TOWING
In this section you will find safety tips and
information on limits to the type of towing you can
reasonably do with your vehicle. Before towing a
trailer, carefully review this information to tow your
load as efficiently and safely as possible.
To maintain the New Vehicle Limited Warranty
coverage, follow the requirements and
recommendations in this manual concerning
vehicles used for trailer towing.
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will
assist you in understanding the following
information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your
vehicle. This includes driver, passengers, cargo
and tongue weight. The total load must be limited
so that you do not exceed the GVWR Ú page 153.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight
of all cargo, consumables and equipment
(permanent or temporary) loaded in or on the
trailer in its "loaded and ready for operation"
condition. The recommended way to measure GTW is to put
your fully loaded trailer on a vehicle scale. The
entire weight of the trailer must be supported by
the scale.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front
and rear axles. Distribute the load over the front
and rear axles evenly. Make sure that you do not
exceed either front or rear GAWR Ú
page 153.
Tongue Weight (TW)
The TW is the downward force exerted on the hitch
ball by the trailer. You must consider this as part of
the load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied
by the maximum width of the front of a trailer.
CAUTION!
Do not load your vehicle any heavier than the
GVWR or the maximum front and rear GAWR. If
you do, parts on your vehicle can break, or it can
change the way your vehicle handles. This could
cause you to lose control. Overloading can
shorten the life of your vehicle.
WARNING!
It is important that you do not exceed the
maximum front or rear GAWR. A dangerous
driving condition can result if either rating is
exceeded. You could lose control of the vehicle
and have a collision.

22_MP_OM_EN_USC_t.book Page 154

STARTING AND OPERATING155
Trailer Sway Control (TSC)
The TSC can be a mechanical telescoping link that
can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable
friction associated with the telescoping motion to
dampen any unwanted trailer swaying motions
while traveling.
If equipped, the electronic TSC recognizes a
swaying trailer and automatically applies individual
wheel brakes and/or reduces engine power to
attempt to eliminate the trailer sway.
Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue
weight, just as if it were luggage located at a hitch
ball or some other connecting point of the vehicle. These kinds of hitches are commonly used to tow
small and medium sized trailers.
Weight-Distributing Hitch
A Weight-Distributing system works by applying
leverage through spring (load) bars. They are
typically used for heavier loads to distribute trailer
tongue weight to the tow vehicle's front axle and
the trailer axle(s). When used in accordance with
the manufacturer's directions, it provides for a
more level ride, offering more consistent steering
and brake control thereby enhancing towing
safety. The addition of a friction/hydraulic sway
control also dampens sway caused by traffic and
crosswinds and contributes positively to tow
vehicle and trailer stability. Trailer sway control and
a Weight-Distributing (load equalizing) Hitch are recommended for heavier Tongue Weights (TW)
and may be required depending on vehicle and
trailer configuration/loading to comply with Gross
Axle Weight Rating (GAWR) requirements.
TRAILER TOWING WEIGHTS (MAXIMUM TRAILER WEIGHT RATINGS)
WARNING!
An improperly adjusted Weight-Distributing
Hitch system may reduce handling, stability,
braking performance, and could result in a
collision.
Weight-Distributing systems may not be
compatible with surge brake couplers. Consult
with your hitch and trailer manufacturer or a
reputable Recreational Vehicle dealer for
additional information.
